Answer:
3)Some gas molecules move further apart and some move closer together.
Explanation:
because When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container. This force is called pressure. There are several units used to express pressure.
.4 M means that in 1 Liter of solution there are .4 moles.
Molarity x Liters = Moles
We have molarity, so convert mL to liters
250 mL x 1000mL/1 Liter = .25 L
Now, set up the equation
.4 M x .25 L = .1 moles of solute
